Was bedeutet der Fehlercode?
The driver and passenger door modules check the signal from the interior central locking button for unlocking. The fault is stored when the button has been held pressed for a long time, or when the signal wire has been short-circuited to ground for a long time. The module then ignores the signal from the button until it is no longer pressed.
Mögliche Ursachen
- The button is stuck in the pressed position
- The signal wire is short-circuited to ground
- Moisture and/or oxidation in the connections
- The local locking switch is damaged
Was Sie tun können
- 1Check that the button in the door panel can be pressed in and released, and that it is not stuck in the pressed position
- 2Check that the fuses are intact
- 3Test the central locking with the remote or the key and see whether the fault only concerns the button
- 4Check the connector to the button for moisture and oxidation
- 5Use a multimeter to check that the signal wire has no contact with ground
- 6If the fault remains, have a workshop with diagnostic equipment check the button and the door module
